WeedSeeker®

WeedSeeker® Sensor

WeedSeeker® Sweeper

WeedSeeker® is an automatic spot spray system that not only cuts weed-control costs by up to 90% and lowers labour costs, but also reduces the environmental impact of herbicide application.

The Trimble® WeedSeeker® spot spray system is an effective solution to help you efficiently control weeds. The WeedSeeker® system senses if a weed is present and signals a spray nozzle to deliver a precise amount of chemical—spraying only the weed and not the bare ground. It is most effective in areas where weeds occur intermittently.

How WeedSeeker® works:

The WeedSeeker® system uses advanced optics and computer circuitry to sense the presence of a weed. When a weed enters the sensor’s field of view it signals a spray nozzle to deliver a precise amount of herbicide to that weed only. WeedSeeker® technology uses sensors and nozzles spaced at either 300mm or 380mm apart. This is due to the narrower field of view associated with the WeedSeeker® sensors compared to a 500mm spacing on a standard boom, allowing you to maximise potential chemical savings. Herbicide is reduced by between 60-90% on most spray applications.

The WeedSeeker® is being used in agriculture as well as orchards, vineyards, along roadsides, railways, airport runways, car parks, parks, hiking tracks, etc. The possibilities are endless.

Key benefits

Reduce herbicide costs – up to 90%

Reduce herbicide resistance potential – by applying the right product at the right rate to kill the weeds

Environmental sustainability – by reducing chemical load in the environment

Water savings – by covering more hectares per tank load

Time savings – by reducing tank filling rate times

Can be adapted for Smart-N functionality

Operate day or night at speeds up to 21 km/hr* (15 to16 kph is the optimum top speed)

Retrofits to existing equipment

Ability to use more effective sprays without damaging the crop
*Higher speeds are achievable by remotely mounting the spray solenoid

WeedSeeker® Model 650:

The WeedSeeker® Model 650 sensors operate on a 12V power supply and configured for a 300mm spray pattern, matching its 300mm field of view. The 650 model is ideally suited for use in vineyards where sensors are mounted 455-760mm from the ground. Systems may have a single or multiple sensors mounted on the spray system.

WeedSeeker® Model 655:

The WeedSeeker® model 655 sensors also operate on a 12V power supply. They are configured for a 380mm spacing to match their 380mm field of view. The sensors operate at 610-760mm from the ground and can have single to multiple sensors mounted across a spray system. The model 655 sensor is used primarily in broad-acre applications so the sensors can be spaced further apart, allowing a reduction in additional weight added to spray booms by the WeedSeeker® system while still maximising chemical savings.
